$PECIFICATION forming part of Letters Patent No. 535,707, dated March12, 1895.

Application filed January 30, 1894.

To (0 whom, it may concern.-

Be it known that 1, CHARLES MACTAGGART, a citizen of the United States,residing in the city and-county of Philadelphia,State of Pennsylvania,have invented a new and useful Improvement in Girder Clamps and Hangers,which improvement is fully set forth in the following specification andaccompanying drawings.

My invention relates to improvements in girder clamps and hangers, andconsists of the combination of parts as will be hereinafter set forthand pointed out in the claims;

Figure 1 represents a perspective View of a girder clamp and hangerembodying my invention. Fig. 2 represents a partial side elevation andpartial vertical section of a detached portion thereof.

Similar letters of reference indicate corresponding parts in the twofigures.

Referring to the drawings: A, A designate hangers or clamps, which areadapted to embrace the flange of the beam B. Connected or formed withthe hanger A is a bar 0, which passes freely through the other hanger A,and also through the opening D in the head E, to which is screwed orotherwise attached the depending rod F. On the hanger A isa set-screw G,which is adapted to enter either of the openings H in the bar 0, theupper edge of said bar having notches or grooves .l thereon to receivethe tooth K on the upper wall of the opening D in the head E, it beingevident that the clamps may be readily adjusted to the width of thebeam, and as there is a deep space D below said bar, the head may have avertical play so as to be raised and thus clear the tooth K from thenotch J which it occupied, so that said head may be moved to the rightor left, and the tooth seated in the adjacent notch, the head thus beingadjusted between said clamps, so that the rod F may be properly locatedit being evident that when the parts are adjusted, they readily retaintheir position.

The bar 0 is angular in cross section and the openings in the clamp Aand head E are also angular so thatsaid head and clamp will not overturnin applying the device to the beam B, it being evident that as suchappli- $erial No. 198,448. (No model.)

cation is overhead, the overturning of said clamp and head would be amatter of great inconvenience and labor which it is desirable to avoid,and this is accomplished by the angular features stated, it being alsoevident that as the head E is non-rotatable, the rod F is'prevented fromswinging.

On the rod F are arms L, which are formed with openings M, the walls ofwhich have bosses thereon, thus forming enlarged bearings for wires,&c., passing through said arms.

The arms L may be vertically adjusted, and they provide means forsupporting water, gas, or other pipes, electric conductors, wires, &c.

The lower arms L have notched ends for attachment of a chain N, whichlatter forms a loop to support a pipe, 820., therein, said loop beingadjustable by attaching the proper links on said arms, so that pipes,&c., of different diameters may be supported therein.

As the pipes, 860., supported on the arms may expand and contract, Iprovide for the consequent movement of the same by means of rollers P,which are journaled on the upper sides of said arms, and have the pipes,850., resting thereon, the effect of which isevident. The arms whichcarry said rollers P have a screw-threaded boss for connection with therod F, so that a partial vertical adjustment of said arms may be made,while pipes, &c., are supported thereon, without displacement of saidpipes, 850., the rollers preventing any binding of the parts.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

l. The clamp-carrying bar C,in combination with the head E havinghorizontal and vertical openings therein, the horizontal openingreceiving the bar, and havinga deep vertical space below the same, thetooth K depending from the upper wall of said opening adapted to engageeither of the notches of said bar, and the depending rod F secured inthe vertical opening of said head, said head being vertically movable onsaid bar, owing to said space, so as to raise said tooth clear of thenotch it occupies, for lateral adjustment of said head and subsequentinterlocking of the same with said bar, the said bar 0 and the openingsin the clamp A and the head E being angular zontal roller journaled onthe upper side of in cross section, and the parts named oomsaid arm,said parts being combined sub- IO billed substantially as described.stantially as described.
